Question details

Is possible execute supervision and control action with the 800xA Wireless Hart solution?

This question Is about the implementation of Wireless Hart Solution with 800xA. Basically the we want implement a solution with Wireless Hart but not only for supervision, they want execute Control over Valves using wireless Hart, I made a research before write this question and I found a presentation (I am attaching an slide image) where indicate the following “Achieve cost effective seamless AC 800M control applications. Wireless HART measurement can be included in seamless control applications in AC 800M with any other fieldbus protocols or I/O signals. AC 800M includes preconfigured read and write function blocks to read HART variables from the Wireless HART gateway” this indicate that apparently the solution is not limited to only supervision, that is possible execute controller action through the Wireless Hart Gateway, however, I want to be really sure because don’t exist any other kind of document where this is confirmed, in summary:

Is possible execute supervision and control action with the 800xA Wireless solution showed in the picture below and the presentation attached?

Just to add to the Answer Yes, only with the restriction of the cyclic Hart time communication.

This means for PID loops which have a reaction time faster then 10 seconds (fast processes) this solution would not be recommend. It could be tuned the wireless Hart to upto 5 or even up to 1 second but I would be very carefull with this implementation.
